T0 all whom, t concern: v

Be it known that I, Emitir Montero Bos- SUET, engineer, of 49 Boulevard Haussmann, in the city of Paris, Re ublic et' France', have invented e. Dirigible alloon, of which the following is a full, clear, and exact description.

This invention relates to s dirigiblc balloon.

This new dirigible balloon, the principal body of which is constituted by two conical vessels lled with gas and having their bases opposed and to which vessels a rotary motion is imparted from a motor carried by the balloon, is essentially characterized by, first, its mode of ropelling by means oi' helical wings arrange throughout the length of the conica-l vessels forming the principal body on two, three, or four lines, so as to form e screwwith interrupted multiple threads, the wings of each line being stepped; second, the arrangernent oi the framing yfor stiliening or bracing the parts, avoiding any distortion of the whole system and making the same perfectly rigid, while entirely preserving the balloon and its car. a

VThis system off/balloon is represented, by wey of eXan1ple/in the accompanying drewings, inwhich Figure l is longitudinal elevation, the central portion being shown in section. Fig. 2 is s horizontal longitudinal section. Fig. 3 is a view of the iront end. lli s. 4 and 5 are two cross-sections, respective y, niade ac cording to the lines A B C l) of Fig. l.

in the iiguresthe sanie letters of reference denote the seme arts.'

The framework of the balloon is constituted by o. longitudinal stationeryanis a, extending the whole length of the balloon and carrying, first, et its central part two vframes l) b', noch composed ci radial arms4 colmo/ted together by steel wires c, Fig. hrl, both t ames t Z1 being connected together by ineens of ties d; second, et both ends two other frames e c of smaller size,also composed. ot stationery radial arms connected together by means of steel wires.

The fra-Ines t e are connected together by Ineens of stretchers or staysf, fastened to the end of the arms of these frames end finally to the iront end of the longitudinal shaft a. Any stretching or tightening device can be used to regulete the tension oi' seid stays,

The l'ralncs t e site also connected together by ineens ci stretchers or steysj". The axis a thus provided with its trames l) ll e e possesses en absolute rigidity and a very great resistance toilexure.

The horizonte-l arms of the four frames have extensions, respectively connected the one to the other by nieans of auxiliary stretchers f2, in view of allowing to arrange a horizontal strip f3, of light metal or any cloth, extending on each side and upon the whole length ol the balloon. This band has for its purpose to maintain a straight direction, to avoid any rolling, and to serve as a parachute.

The body ol the balloon consists of, first, two trustunl-shaped bodies or vessels g g', respectively, arranged between the frames t e and b second, a central body or vessel h, included between the two frames l) b. f

The cones g g consist of a casing of aluminium, rubber cloth, silk, or any other suit able material carried by a frame of any kind and mounted upon a central tube t' i. The tubes i fi, mounted on the axis o, can rotate freely on tbe latter through ballbearings- The cones can be divided by niveaus oi inner walls into several distinct compartments. By wey olI safety each of them is provided with a valve opening externally, end the spring of which is so arranged as to allow this valve to open when the internal pressure goes beyond a certain extent.

Each conical body g g carries externally a series oi helical wings g2, arranged on e ce1- tziin nuniber ot lines, so es to constitute n screw with interrupted multiplex threads ond extended pitch, es to allow a rapid prog-- ress of the balloon without requiring a great speed of rotation of the conical bodies g g". By this special arrangement of helical wings on a line in e stopped wey the wings of a row will leave between them and those of the next row s iree rectilinear space in which air can freely circulate. These free spaces provided between the wings constitl'ite on the surface of the balloon rectilinear ways in which airis engulfed. Accordingly every wing whatv ever its distance from the top ot the trust-u1u may be strnies in rotating the air introduced in these passages. In these conditions all the wings work and have the greatest efficiency.'

lOO

The two conical bodies g g, which constil bevel-pinion z-, gearhig with e z2, fast tute the propelling parts, have imparted to them a rotary motion controlled as hereinafter specied. On the contrary, the central body h. is firmly secured to the two frames The car y' is suspended through two standards le, Fig. 5, which can freely swing upon the cross-shaft l, carried by the crossbirs m, which connect the two central frames The position of the car relatively to the body of the balloon is insured by four ropes n 'nJ n" n', fastened to the frames l) t and winding over a small windlass 0, carried by the standards ot the car. When this windlass is turned in either direction, a pull is eX- erted either on the ropes fc or en the ropes n', whereby the car is shifted between the frames 7) t and accordingly the center of gravity of the balloon either toward the fore part or toward the aft, the balloon then pointing downward. or upward and ascending or descending in virtue of the rotation of the cones g g, provided with helical wings.

Each conical body g g derives its rotary motion from lthe following device: Each tube e' i of the conical bodies g g carries e bevelpinion i, meshing 4with the pinion p,l fast with the pulley r, driven by the belt g, passing over prille r l1', which is fast with a pulley s, deriving its motion from a pulley through the medium of a belt s. The two pulleys t are keyed upon the shaft of the upper cone u. of a speed-changing gear, the lower cone u or" which, driven by a inotor of any kind o, actuetes the upper cone u. through the ine .diuin of the belt uadapted to be displaced along these cones in order to allow to Ywary the speed'iniparted to the conical bodies g g and also the speed of the bztllcon.

It is well understood tlj t any system oi speed-changing gear can used and that the same een even be dispensed with if the motor is' so arranged as to enable to regolate its speed.

lThe central trames tf further carry four side propsm, the ends of' which are et the same level as thfbottoni of the car and serve as a rest for the balloon when on the grounds These side props can be pivoted, so as to be able to be folded.-

A rudder y is arranged at the baci; art or the balloon for steering the same cit er towerd the right or the lett.

The balloon can also be provided above the central body it with e screw 2, turning .in a horizontal plane and adapted to cause the balloon to ascend when the letter is heavier tl en air, screw being driven tlnough any able ineens. rihis screw s will be keyed, mstance, upon a shaft passing through the central body lt and carrying at its end a with one of the two pulleys r. Any suitable clutch will allow of setting this screw z into motion at the required moment.

The forms, sizes, and det ils can of course vary eocori'l ing to the requirements,
